As shown in the figure, the mortar base (also referred to as waste concrete) 50
A curb main body 51 made of concrete is arranged on the top, and the kerb main bodies are joined together so as to fill gaps (joints) with a mortar 52.

[0003]

The conventional curb body 5 described above.
1 is heavy and difficult to handle because there are no irregularities suitable for hanging hands or tools. Moreover, since the flat end surfaces 51a of the curb main body 51 are joined to each other with the mortar 52 so as to abut against each other,
Alignment work requires skill and is inefficient.
In addition, if the position is corrected after the joint is applied, a sufficient adhesive force cannot be obtained, and a deviation is likely to occur due to vibrations from the roadway side, and the aesthetic appearance and function of the road curb are impaired.

[0004] The conventional road curb has a function of providing a step on the road to clarify the boundary and preventing the vehicle from entering to some extent. It is not conceived to provide an information function for issuing an alarm to urge the user or recognizing road information or the like. In addition, although the reflection plate is attached depending on the installation location, it means that it is fixed to the surface of the concrete with a stud.

[0005] The present invention has been made in view of the above circumstances, and facilitates the work of laying a road curb,
An object of the present invention is to increase the connection strength of the connecting portion to make it harder to break. It is another object of the present invention to enable a warning device such as a light emitting device or a radio wave transmitter to be built in a road curb.

[0006]

For this purpose, the following road curb set was created.

[0007]

[0008]

Examples of the alarm device in the present invention include a light-emitting display device, a radio transmitter, a speaker and a buzzer. The wireless communication means for transmitting various kinds of road information to passing vehicles is also included in the alarm device.

[0010] The invention according to claim 1 is a road curb set comprising a plurality of curb bodies and a connecting spacer arranged between adjacent curb bodies. It is characterized in that engagement portions having shapes that fit into each other are formed.

When the above-described road curb set is extended on a road or the like, the curb main bodies located on both sides of the spacer are aligned by fitting the curb main body and the engaging portion of the spacer, that is, the centering operation of the road curb is performed. Can be easily done,
The bonding strength also increases. An adhesive is used to join the curb body and the spacer. However, the unevenness of the engaging portion increases the number of adhesive surfaces and makes it difficult for the connecting portion to be displaced.

Further, the invention according to claim 1, in the road curb set, said the curb body and the spacer has a through hole which communicates so as to connect the connecting ends formed, and its spacers Is characterized in that a communication passage extending from the outer peripheral portion of the spacer to the through hole is formed.

Therefore, the cables such as the power cable and the communication cable can be laid in the road curb easily and inexpensively, and can be easily pulled out from the communication passage of the spacer as necessary. Become like In addition, in order to maintain cables,
It is preferable to construct the spacer so that the spacer has a divided structure and a part thereof can be removed.

According to a second aspect of the present invention, in the road curb set, an alarm device is provided on a cover member detachably mounted on the spacer.

In this case, various alarm devices (for example, a light-emitting display device, a radio wave transmitter, a speaker, a buzzer, etc.) provided on the road curb can be attached and detached together with the cover member, so that installation and maintenance are easy. Become. In addition, since the cables connected to the alarm device do not crawl on the surface of the road curb, the appearance is not spoiled.

The spacer 4 has a shape corresponding to the shape of the end of the curb main body 1, has a substantially cruciform shape that can be fitted into the engagement recessed portion 1c, and has a thickness almost twice the height of the projection of the engagement projection 1b. As shown in FIG. 5 and FIGS. 5A and 5B, a cylindrical portion 4a for fitting into the pipe 2 protrudes from both front and rear surfaces. By the hole 4b of the cylindrical portion 4a,
The pipes 2 of the adjacent curb main bodies 1 can be communicated straight. Further, the spacer 4 is provided with holes 4 of the cylindrical portion 4a from upper, lower, left and right end surfaces 4c and 4d of the spacer 4.
Communication holes (also referred to as communication passages) 4e and 4f extending to b are formed, and screw holes 4h having a predetermined depth are provided on the end faces 4c and 4d. This spacer 4 is, in FIG.
Left and right and front and back are symmetrical. Although the spacer 4 of this embodiment is integrally formed of a synthetic resin, the strength may be increased by using a metal pipe for the cylindrical portion 4a, or the entire spacer 4 may be made of metal or concrete.

Next, the cover member 6 attached to the spacer 4 will be described. As shown in FIG. 6, the cover member 6 has a substantially U-shape following the cross-sectional shape of the curb body 1, and a hole 6 a for a mounting bolt is formed on a side surface at a position corresponding to the screw hole 4 h of the spacer 4. ing. This cover member 6
Is for covering and hiding the spacer 4 when it is mounted on the spacer 4 for connecting the curb body 1, and for smoothing the surface of the connecting portion to improve the appearance of the entire curb, and using a phosphorescent paint or the like. Appropriate coloring is applied to function as a sign with good visibility. Although the cover member will be described in detail below, the cover member may be configured to be equipped with an appropriate alarm means.
The connection may be made to a power source through a cable in the communication holes 4e and 4f and the pipe 2.

Here, another example of the cover member will be described. The cover member 16 shown in FIG. 7 includes an inner cover 17 and an outer cover 18 having a substantially U-shaped appearance. By combining the two, an accommodation space capable of accommodating an alarm device such as a light-emitting display device is formed. It has become. The inner cover 17 has a substantially U-shaped cross section with a stepped portion, as shown in FIGS. 8 and 10, and the upper and side portions of the inner cover 17 are formed with communication holes 4 e and 4 f of the spacer 4. A window hole 17a is formed at a corresponding position, and a hole 17b for a mounting bolt is formed at a position corresponding to the screw hole 4h. As shown in FIG. 9, the outer cover 18 has a substantially U-shaped cross-sectional shape, and can be mounted so as to cover the inner cover 17 from the outside with reference to 10.
In this embodiment, the inner cover 17 and the outer cover 18 are fixed by bonding, but an appropriate fastening means such as a bolt or a fastener may be used. The accommodation space is, as shown in FIG. 10, a light emitting display device 1 such as an LED.
9 is suitable for mounting. In this case, the wiring of the power cord 19a is connected to the communication hole 4e of the spacer 4 through the window hole 17a.
It is preferable to crawl into the through-hole 2a of the curb main body 1 or to connect to the cable 20 passing through the through-hole 2a.

Next, the operation of the road curb set configured as described above will be described. When constructing road curbs,
The curb bodies 1 are placed side by side on a flat ground. At this time, the engagement protrusion 1b of the curb main body 1 can be used as a gripping margin in a manual operation or a heavy equipment operation, so that workability is better than that of a conventional curb. And the curb body 1 to be connected side
After applying an adhesive over the entire surface of the end surface 1a, the engagement protrusion 1b, and the engagement recess 1c, the spacer 4 is fitted into the engagement recess 1c of the curb body 1, and the cylindrical portion 4a is inserted into the through hole 2a. To be inserted. In this manner, the spacer 4 that is engaged with one surface in contact with the curb main body 1 has a half of the thickness protruding from the end surface 1d. Then, an adhesive is applied to the end surface 1a and the engagement protrusion 1b, and then the ends are joined so as to abut each other. If necessary,
An adhesive is also applied to the spacer 4. As the adhesive, an appropriate sealing agent or resin mortar suitable for filling the gap can be used in addition to the epoxy resin. In this way, the curb main body 1 and the spacer 4 are alternately connected, and fine adjustment (centering) is performed so that the whole is along a reference line (often threaded). The bottom 1 of the curb body 1
Since the end face 1d is formed perpendicular to e, by making the curbstone main body 1 and the spacer 4 come into contact with each other, the posture of the curbstone main body 1 can be easily adjusted even by an operator with low skill. .

The curb main body 1 of this embodiment has an engaging projection 1
b, an engaging concave portion 1c, and a through hole 2a are formed, and these concave and convex portions (also referred to as engaging portions) are fitted into the main body portion of the spacer 4 and the cylindrical portion 4a. That is,
Since the posture of the curb body 1 is regulated by the engagement state,
Compared with the conventional construction in which the flat end faces of the curb are abutted, the centering work can be easily performed even with a low level of skill, and the road curb is less likely to break after the construction. That is, the construction quality is stabilized. Further, since the pipe 2 is embedded when the curb body 1 is manufactured, reinforcement and weight reduction can be achieved. The diameter and the number of pipes may be set as appropriate.

Thereafter, as described below, the cover member 6
The connecting portion (seam) of the curb main body 1 is covered with a cover member 16 (see FIG. 11) or a cover member 16 (see FIG. 12). When using the cover member 6 The cover member 6 is bolted to the screw hole 4h of the spacer 4. An appropriate fastener or adhesive other than the bolt may be used. It is to be noted that several types of the cover member 6 which are appropriately colored in advance are prepared, and the color can be made to function as a sign by selecting a color scheme according to the section of the road. For coloring, it is preferable to use a phosphorescent paint, a fluorescent paint, or the like in order to enhance discrimination, and it is necessary to consider weather resistance.

When the cover member 16 is used The cover member 16 is used mainly for incorporating a warning device such as a light emitting display device into a road curb. In order to attach the cover member 16 to the connection portion of the curb main body 1, first, the inner cover 17 is bolted to the screw hole 4h of the spacer 4, and the outer cover 18 is covered from above (see FIG. 10).
In this example, the light emitting display device 19 is attached to the inner cover 17, but may be attached to the outer cover 18 or the spacer 4. The power cord 19a of the light emitting display device 19 is
a, and then crawl into the through hole 2a of the curb body 1 after being guided to the communication hole 4e of the spacer 4, or connect to the cable 20 passing through the through hole 2a. In this way, by storing the cables in the road curb, installation and maintenance are facilitated. Further, since the cables are not exposed, the appearance is good, and light can be emitted from the seam of the curb body 1, so that it is highly useful as a guide sign or the like.
In addition, by appropriately selecting the cover member 6 or the cover member 16, it is possible to freely and finely set a place where light is emitted.

Next, another example of the spacer will be described with reference to FIG. The spacer 14 shown in the figure has a divided structure of a spacer main body 14A and an upper member 14B. When the spacer main body 14A and the upper member 14B are combined, the spacer 14 has a shape similar to that of the spacer 4 and is brought into contact with both front and rear surfaces. The curb bodies 1 are firmly connected to each other, and
Through holes 2a can be connected straight. The spacer body 14A is formed in a substantially T shape,
A cylindrical portion 14a protrudes from both front and rear surfaces, and a hole 14b penetrates in the front and rear direction. Then, communication holes (also referred to as communication passages) 14f, 14e, and 14 extending from the left and right end surfaces 14d, the lower surface 14c, and the upper surface 14k of the spacer body 14A toward the through hole 2a.
j is formed, and screw holes 14h or 1
4i are formed. On the other hand, the upper member 14B is a rectangular parallelepiped having the same thickness as the spacer body 14A, and has a communication hole 14m vertically penetrating therethrough and a mounting hole 14p. When connecting the spacer body 14A and the upper member 14B, a bolt (not shown) inserted into the mounting hole 14p is screwed into the screw hole 14i.

Next, the usage of the spacer 14 will be described. When laying a road curb on a road surface or the like, a spacer 14 for connection is interposed between the adjacent curb main bodies 1 and the curb main bodies 1 are joined to each other using an adhesive as in the case of the spacer 4 described above. . At this time, the upper member 14B
Is separated from the spacer body 14A so that the adhesive does not adhere to the spacer body 14A.
Connect to The above-described cover member 6 or cover member 16 is appropriately selected and mounted on the spacer 14. In this example, after the curb body 1 is connected via the spacer 14, the upper member 14B can be detached. That is, the cable can be pulled out by removing the upper member 14B almost at the stage when the laying process of the road curb is almost completed, so that the installation and adjustment work of the alarm devices becomes easy. Further, after the installation, maintenance of the communication cable and the like can be easily performed.

The light-emitting display device 19 not only emits light by a built-in lighting device such as an LED, but also informs a driver of information such as approaching an intersection or a traffic congestion step by step by changing an arrangement interval. be able to. In that case, a control device that can finely control the light-emitting display device 19, such as changing the light-emitting color according to the situation, may be provided. Further, a configuration having communication means for providing various information to the driver may be adopted. In the present embodiment, a straight road curb is illustrated and described. However, the curb may be installed so as to draw a curve, and a similar effect can be obtained. In addition, it is needless to say that the present invention can be implemented in various modified embodiments based on the knowledge of those skilled in the art.

[0028]

As described above, according to the present invention,
The work of laying the road curb can be facilitated, and the connection strength of the connecting portion can be increased to make the connecting portion hard to break. Further, since a warning device such as a light emitting device or a radio wave transmitter can be built in the road curb, it can contribute to traffic safety.
